Application filed February 16, 1%14. Serial No. 818,966.

To all whom it may concern Be it known that I, JOHN SCHMIDT, a citizenof the United States, residing in Pittsburgh, in the county of Alleghenyand State of Pennsylvania, have invented a certain new and usefulSpacing and Punching Machine, of which the following is a specification.

My invention relates to apparatus used in conjunction with punchingmachines and similar apparatus,in locating the position of the holeswhich are punched or otherwise formed in plates, angles, beams andsimilar metal materials, preparatory to the later fabrication of thepunched materials. One object of my invention is to provide a universalgage or spacing machine for power Dunches and similar hole formingapparatus having novel means enabling a plurality of rows of openings orholes being formed in the material being punched while the material isbeing moved but once from end to end across the path of the punch orperforating apparatus.

Another object of the invention is to provide a gage or spacing machinefor punches having novel means whereby the formation of a seriesof-staggered holes in the materials being punched is effected withoutthe use of gage lines andwith but one end to end movement of thematerial across the path of the hole-forming device.

Another object of the invention is to provide a punching machine havingimproved means for accurately punching the holes of a plurality of roWsin'a successive manner and without the use of'gage lines or punch markson the material.

A further object'of my invention is to provide a punching machine havingmovable top and bottom punching dies, and having improved means wherebythe dies are moved in unison relative to the-material in bringing thematerial into position, :and having novel means for determining theposition of holes formed in the material by the movable dies.

A still further object of mv invention is i to provide a gage andspacing machine adapted for use with existing punching machines.

Still further objects of the invention consist in the novel-combinationand arrangement of parts more fully described hereinafter andspecificallypomted out inthe ap i pended claims' Referring now to thedrawings, forming part of this specification, Figure l isa frontelevation showing a vertical punching machine having a universal gageand spacing machine applied for use thereon and constructed and arrangedin accordance with my invention. Fig. 2 is a side elevation of theapparatus shown in Fig. 1 showing the spacing table as located withinthe throat of the punching machine and the arrangement of the gage orspacing mechanism. Fig. 3 is a sectional plan of a po tion of theapparatus, taken on the line I-III of Fig. 2 showing the movable punchon the upper vertically reciprocating head of the punching machine inone extreme position into which it is moved, and the connectingmechanism between the punch and the gage forming part of this invention.Fig. 4=is a simia plan partly in section showing the bottom die in itsother extreme position on the bottom anvil of the punching machine.

In the accompanying drawings, the numeral 2 designates the 'frame orhousing of a vertical punching machine having a bottomv head or anvil 3and, above the anvil 3,

is a vertically reciprocating opposing ram u n o I, lar sectionalelevation taken on the lineor head 4., the throat '5 of the punchingmachine being formed in the usual manner, between the bottom head 3' andthe reciprocat' ing ram 4. g

Positioned so as to extend lengthwise horizontally within the throat 5and on opposite sides of the punching machine, is a spacing table 6which is movably mounted on a track formed by angles 7, 7, and rollersor track wheels 8. The wheels 8 are located at separated intervals inthe length of-each of the angles '7 and vertically extending supports 9conveniently formed of rolled steel angles, are provided at suitableintervals in the length of the angles 7 forming the spacing table track.The track wheels 8 have pcriplu eral grooves therein engaging with theedgeofthe vertically extending legs of angles 10 which form the slidesfor the grid forming the spacing table or work support 6. The table 6which is lengthwise movable upon the idlerwheels 8 of the track, ispreferably made in the form of a grid so as to support the materialsbeing punched without interference with the punching operations.

Positioned on the upper face of the bottom head 3 is a block 11 having arecessed groove in, its upper face, and slidingly inountedin therecessed groove is an anvil support 12. Removably mounted on the anvilsupport 12 is a bottom die 13 having an opening or hole in the-upper endthereof, "asis shown'in Figs land 6. v 3

Mounted in the recessed groove in the lower end of the reciprocatinghead 4 is sliding block 1 1 and removably, secured on this block is apunch 15 by which the holes are formed' in the materials punched.Secured upon angle brackets 16 and 17,

which are rigidly mounted on the front face of the punching, machine, isa square vertically extending shaft 18, having reduced end portions bywhich the shaft is rotatably secured in the brackets. 16 and 17, andsecured on the shaft 18 adjacent to the lower end thereof is a leverorarm 19' which is connected by a link 20 with the sliding block uponthe lever and are moved into operative 1 osition by means of theirrespective grip evers 2.6, 27. The shaft 18 as shown s dividedtransversely into sections, the reduced upper end of the lower sectiontelescoping within the recessed lower end of the upper section so as topermit the upper section of the shaft 18 and attachments reciprocatingwith the top ram 4 of the punching machine.

' Secured by a knee or support .28 to the outside one of the trackangles 7 is a quadi=ant forming adialor gage plate 29, which is providedwith a series of staggered holes arranged in concentric circular arcsonthe quadrant or dial 29.. The holes in the quad rant cooperate withthe indexpins 24, 25

on the lever 23, as will be described, two

rows of the holes being provided to reduce the size and enable thequadrant being made as small as possible. Secured by an anglesupport 30.to the vertically, movable top platen or head 4 isa third index pin 31which is arrangedto project downwardly into proximity with the upperface of the spacing table 6. This pin is connected by the link 31 to thepivoted leve'r34 and the firai is connected to the treadle 33 by a Atemplet 32 having the lengthwise spacing of the holes to be punched issecured positioned on top of the table 6 or 'a tape, marked in a similarmanner, may be laid lengthwise on the table 6 in place. of the templetto determine the position, center to center, of the holesin thelength ofthe material being punched.

In the operation of my'improved appara- "tus the angles, plates "orother material 35 to. be .punched are placed in position on the spacingtablet) and are clamped to the upper surface of the table 6. The templetor when used the tape is likewise secured in position along the outermarginal edge of the work table 6.

' The staggered holes 111 thegage plate 29 are generally spaced 'atdistances equal to a inch center to center, and, as for example,

when the gage lines of the two or more rows of'holes to be punched inthe materials equal two inches, the appropriate holes in the gage plate29 aremarkedwith chalk or in other suitable manner so as to be readilyidentified. The operator then moves the arm 23 until the right one ofthe index pins, 24 or 25,'registers with the marked hole in the gageplate 29. The work table 6 is then moved lengthwise on its track untilthe index pin 31 is-in line with" the required mark on the templet ortape. The operator moves the index pin 31 which is connected by the link31" to the. lever 34, downwardly by pressing the treadle 33 until theindex pin engages the proper hole i the templet when a templet is usedwhere 't remains so as to form a stop which holds the work" in positionduring the punching operation. The movement of-the treadle 33 alsocauses the punch 15 to be set in motion, and as it descends a holeispunched in the material on the table 6, beneath the punch. When thepunch 15 is retracted, it automatically stops at the end of its upwardstroke, in

the manner common to all punching ma-- chines, in which position itremains until released by the operator. After'the punch has beenretracted, the work support 6 is moved lengthwise on its track until theindex pin 31 again registers with the desired mark on the templet 32- ortape, and the lever 23 is again moved to shift the position of thepunch15 and the bottom die 13 beneath the punch, one of the index pins 24, 25on the lever 23 registering with a hole in the dial 29 in indicatingwhen this position is reached. The foot lever 33 is then'again pressedvby the operator to again start the punch in operation and form the nexthole in the material being punched, in this case forming. the hole inthe second of the two rows of holes to be formed in the material. Theabove described operations are then' repeated as often as is required toform the necessary number of holes in the material being'punched. Thepunched material 1 punched material, when .the above operais thenremoved and is replaced by untions are repeated.

.In.- fabricating structural material and I punching plates for boilers,tanks and similar apparatus, there" usually is a consider:
